The mobile market is saturated with big players and attention seeker games. If you do not walk that path, you will have a hard time to get attention to your game.
Maybe it can help if you concentrate on making a game first and a mobile game later. What is it about your game, that makes it a "mobile" game? Does it need the gyro sensor in a phone to work or what? Is it about attention span and casualness? People play silly games on desktop too.
While Itch has capabilites to upload some mobile games, it is specialized for desktop. Oh, people do ask for mobile versions of games all the time. But they searched out the game for the game's sake and not because it has a mobile version. So you might find a certain bias for non mobile games here.
